4
Without an understanding of agriculture n all humans would be struggling for survival

5
Most of our comforts come as a direct result of science. n shelter n food n clothing

6
Early people ate fruits, nuts and other seeds. n They were migratory hunters n The idea of domestication came about and people began to settle down

7
People began to pay close attention to details n and from these details n drew conclusions on where to locate and harvest their food.

8
Progressive scientific research n in the U.S. began in the mid 1800s at universities. n The universities were only teaching the classics such as Latin and Greek, History, Math and Philosophy

9
Soon they realized n that they should include more practical hands on subject areas in their curriculum.

10
1862 Senator Morrill from Vermont n pushed for a bill through the U.S. Congress that would provide public land and funds for colleges that would teach practical methods of manufacturing and food production

11
The bill was signed by President Lincoln n and the Land Grant or Morrill Act was passed into law.

12
1862 n A bill was passed which started the USDA n United States Department of Agriculture

13
1872 - Hatch Act n With the growing interest in agriculture, the government decided to put the new ideas for agricultural practices to work.

14
Hatch Act n This act set up the Experiment Stations run by the universities

25
Two groups to every experiment n control - is constant in everything except the thing being tested

26
experiment - n contains everything that the control group does, but also contains the variable being tested

27
Two types of research n basic - looks at why or how processes occur in animals n applied - uses the discoveries made in basic research to help in a practical manner.

28
Where Search Has Led Us n Agriculture, besides medicine, is the application of almost all the research and knowledge associated with plants and animals

29
basic research n has benefited us the most by allowing us to produce high quality protein food very efficiently

30
Research n Here is a list of achievements accomplished since 1925 better control of parasites and diseases and an end product that is higher is protein better control of parasites and diseases and an end product that is higher is protein

31
productivity and efficiency –of all species has increased broilers are ready for market in 7.5 weeks after only 2lbs of feed and it used to take 4lbs of feed and 15 weeks

32
Research W The countries in North and Central America, Europe, Australia and New Zealand have only 29.9%of the worlds cattle yet produce nearly 68% of the worlds beef and veal

33
these are also the countries n in which nearly all of the scientific knowledge about the growing of these animals has been discovered

49
4. Embryo transfer n allows for genes of superior dams to be more widely used

50
combining ET and AI n allows producers to make rapid gains in the quality of their herds in short amounts of time at relatively low cost

51
5. Use of computers –first computer was developed in the 1940s and became an integral part of agriculture in the 1980s –as research moves more swiftly computers allow us to analyze information in seconds instead of weeks

52
And –allows us to do simulated experiments plus numerous other things –ag uses n progeny records n production records
